摘要：

Dehydrogenation in MgH2 was found to lead to a transition from an incubation stage controlled by nucleation to an accelerated stage controlled by the movement of the interface. Addition of carbon nanotubes destabilized Mg-H bonding and reduced the energy barrier for nucleation, which is mainly related to the electron affinity of their curved surface.
